Tangential Water Wheels 




Abner Doble Company 
San Francisco 

Established J8SO 



BULLETIN NO. 5 
1904 



Modern hydro-electric power generation and transmission has led to great 
improvements in water wheels. 

A demand has arisen for large units of highest economy, close regulation 
and absolute reliability in service. 

Tangential water wheels to operate under high heads of water have to a 
large extent been developed to meet this demand. 

The Abner Doble Company has made a speciality of producing first class 
machinery to meet the requirements of the most exacting conditions. 

The following pages illustrate some of the details of work which they have 
executed.

BUCKETS 

All wheels made by the Abner Doble Company are provided with their 
well known patented ellipsoidal buckets. 

These buckets are castings of selected and tested materials; cast iron, 
semi-steel, gun metal, or steel castings as mav be required. 

Each bucket straddles the wheel rim and is machined to fit tightly on both 
sides and on the periphery. Each is fastened to the rim by two fitted bolts in 
reamed holes. 

The buckets are interchangeable, being accurately fitted and drilled in jigs, 
and finally brought to the same weight so that the wheels shall be dynamically 
balanced. The hydraulic surfaces of the buckets are ground smooth, and the 
dividing wedge and entrance edges accurately sharpened. 

The bucket shown on opposite page in six views was in service 586 
twenty-tour hour days under 1300 feet head. Note the absence of irregular 
erosions and all wear on the back of the bucket, although the water carried much 
detritus.

T ANGENTIAL ELLIPSOIDAL WATER WHEELS 



The illustration on the opposite page shows one of the largest and most 
powerful Doble wheels. Under 1531 feet head two wheels of this size are driving 
two 2,000 K. W. generators at the de Sabla Power House of the California Gas 
and Klectric Corporation. 

The wheel body is a nickel steel torging, ten feet five inches in diameter, 
finished all over, weighing over 10,000 pounds. It is bolted to the flanged end of 
the nickel steel hollow forged generator shaft. 

The wheel runs at a speed of 240 revolutions per minute. The buckets 
are open-hearth steel castings, designed for a jet of water four and one-half inches 
in diameter. 

A 4000 K. W. machine to run at 400 revolutions per minute, driven by a 
six-inch jet or water and designed on the same lines is being erected in the same 
power station.

The illustration on the opposite page shows a Doble wheel at the Mill 
Creek No. 3 Plant of The Edison Electric Company, Los Angeles, after one 
vear's continuous running under a head of i960 feet,at 430 revolutions per minute. 

Capacity 1300 HP. 

Note the perfect condition of the buckets.

NEEDLE REGULATING NOZZLE 

The Doble patented needle regulating nozzle has the advantage of per- 
mitting close regulation, maintaining a high efficiency of the jet over a wide range. 
The regulating is done by moving a core piece axially within the nozzle, and 
thereby changing the annular area of the orifice. An efficiency of 99.3 per cent. 
has been obtained in recent investigations at the Massachusetts Institute of 
Technology. 

The illustration on the opposite page shows a jet issuing from a three-inch 
needle regulating nozzle at the Snoqualmie Falls Plant, near Seattle, Washington. 
The photograph was taken by flashlight, through an opening in the housing; the 
blur on the right shows the buckets and wheel rim running. 

When the photograph was taken the jet was reduced to two and one-fourth 
inches diameter.

T A \ i; E X T t A L ELLIPSOIDAL WATER WHEELS 



• u u 'J ustrat .'°, n on the opposite page shows a small needle regulating nozzle 

with the needle in eight different positions giving jet areas ranging from one-tenth 
to the full capacity of the normal opening. The jet is equally perfect in every 
instance, tree of any spray, splash, or rotating action, which would be very 
detrimental to the efficiency of the jet, and which generally occurs with plain 
nozzles without regulating needle. r 

The regulating needle is either operated by hand, or can be direct connected 
to an automatic governor. 



TANGENTIAL ELLIPSOIDAL WATER WHEELS 



This nozzle shown on the opposite page is designed lor a maximum jet of 
six and one-fourth inches diameter, developing 7500 HP under a head of 1 53 1 feet. 

It is of the needle-regulating-deflecting type, the nozzle body consisting of 
two principal parts; one stationary, the other swinging on a pair of trunnions. 

The governor deflects the nozzle, thereby turning the stream partially or 
entirely away from the wheel buckets, in case of a decrease in load, thus taking 
care or the sudden load fluctuations. The needle is operated by a handwheel and 
spindle, thus taking care of the gradual load fluctuations and permitting the greatest 
economy in the use of water.

WATER WHEEL HOUSING 

Our standard water wheel housing, shown on the opposite page is an example 
of first-class boiler construction. All seams are riveted hot and caulked. 

The heavy cast iron frames are machined at joining surfaces, and the bottom 
frame is faced where it rests on a cast iron base frame.

BEARING 

The illustration on the opposite page shows our standard ring-oiling bearing 
for heavv duty. Made with removable shell, which can be taken out for inspection 
or scraping without removing the shaft. The oil receptacle in the base of the 
bearing is provided with gauge glasses and a system of tubes for circulating 
water, to keep the oil cool.
